Kubuntu 10.04

I just switch to Kubuntu Lucid Lynx (10.04) with Firefox 3.6.8 and amule 2.2.6
I added the package amule-gnome-support
as indicated from version 9.10 and higher
the command whereis ed2k:

Nemesia Nemesia @: ~ $ whereis ed2k
ed2k: / usr/bin/ed2k / usr/share/man/man1/ed2k.1.gz
When I click on a link ed2k
He always tells me that the protocol is not associated.
It is true that there is no ed2k to Edit> Preferences> Applications.

I also tried to create the strings and Boolean strings
with''true''values as for older versions, but nothing happens.
